" Letters Patent No. 109,470; dated November 22, 1870.

IMPROVEMENT IN sEfo-sowERs.

The Schedule referred to in lthese Letters Patent and making part of the Same.

fully described.

' Beit known that we, JHSTIN G. THOMrsoN and Fnnnnnrc M. Baisers, of Stockton, inthe county it Chautauqua and State of NewYork, have invented a new and improved Seed-Sower; and wc do hereby declarev that the following is a full, clear, and exact description thereof, which lwill enable'others skilled in the art to make and use the saine, reference being had to the accompanying drawing forming part of this specification, in which- Figure 1 is a verticallongitudinal section of our improved machine. A

Figure 2 is a vertical cross-section ot' the same.

Figure 3 is a perspective view of the ijpper side of the lever. v.

Similar letters ol' reference indicate corresponding six inches high, supported by partitions, B, to bcmadc either of wood or metal, and placed at intervalsv of about two feet.

1n thc bottom of thc box A is formed a row of holes, N, about three inches apart, through which the seed passes to the ground.l

Mis a slide in the bottom of the box A, which may be made of wood or metal.

n the slide M are formed two or more sets ensei-ies of diierent-sized holes, the holes of each size or series being at a distance apart equal to that of the holes N, so that, by simply adjusting the position of the slide M, the machine may be adjusted for sowing 'diferent-sized seed. j

The slide M is kept in pla'cc 'by the grooves O O in the bottom of the vbox A.

E is a bar, which is made a little shorter than the hoxA, so that it may have a vlongitudinal movementwithin said box A.

YV is a wirefwhich isv passed tln'ough thcbar E,

passed spirally beneath the said bar, aga-in through it, and so4 on for the entire length ot' the said bar E, brming a series ot spiral loops beneath the bar E.

lo the upper side of the bar E, near its ends, and

vat its centen'arc attached long staples, D, which pass through holes in the bolts Z,'.which bolt-s pass loosely through the partitions B vertically,l and are raised or lowered by the nuts "C, turning in slots in `the partition B.

a block or support attached to said side, and its other end projects 'at the 'other side of' said box in sucha position that it may be conveniently reached Aand operated by the operator. l

Gr lis a n'letallic rod or bolt, passing through the lever H and standard Fand bar E vertically, in such 4amanner that it serves for pivoting the lever vH upon the standard F, and, by being lowered, the lower cxtreinityof saidbolt G, engages in one of the holes in the slide M, so that, by themovement of the lever H, the slide M may be adjusted.

L is a spiral spring surrounding the bolt G, and attached to it at one end at the point Y, and attached at the other extremity to thc bar E in such a' manner as to draw downward ou the bolt G.

At the point I in the leger H, iig. 3, is an elevation upon thc upper side of Saidlever, with notches for holding the vrounded extremity of the bolt G in place; also, a depression or iissure at right angles to and much deeper than the aforesaid notches, to admit the rounded extremity of 'the bolt G when it is desiredto lower said bolt for the purpose of moving the slide M. At the point J in the lever H is aslot, broadest atv its inner extremity', through which the 'screw A,passes which pivots the lever- H tothe side of the boxfA.

On the under surface' of the 'lever H is the jp'rojection S, fig-2, atsuch a distance fronithe point I in the lever H, fig.- 3, that, when the lever H is at right angles with the box A, ,and thestandard'F is perpendicular, the said projection will rest against the side of the boxA.-

lha-i, we claim as new, and desire to secure by Letters Patent, is'

1. The eombination ot"the bolt G and spiral spring L, substantially as and for the purposes hereinbct'orc y f set forth.

2. The combination of the bolts Z ZZ andthe nuts -O O 0,'substantially as and or the purposes hereinbe fore set forth.

3, An improved `seed-sowing machine, formed by the combination of the'box A, slide M, spirally-looped wireW, suspendedbar E, standard F, bolt G, spiral spring L, bolts Z Z Z,'and nuts C G C, lever H, with each other, said parts being, constructed and opcrating Substantially.asand for the 'purposes set forth.
